Question

a piece of rope 11/12 yd long is cut into two pieces.  One piece is 4/7 yd long.  How long is the other piece?​

Answer 1

29/84 yd
Convert 11/12 and 4/7 so that they have the same denominator. 11/12 becomes 77/84 and 4/7 becomes 48/84. Subtract 77/84 and 48/84 to get 29/84 and since you cannot simplify it anymore that it your answer

Answer 2

Answer:

(4/7) + x  = (11/12)

(11/12) -(4/7) = x

We need to convert BOTH denominators to 84

(11/12) * 7 = 77 / 84

(4 / 7) * 12 = 48 / 84

77 / 84  -(48 / 84) = 29 / 84
